I've been getting the above error when attempting to insert a photo into the database. What's weird is that the file side of the document is inserted fine, but nothing gets inserted to the chunk side. I looked around the web but didn't get any hints as to what the problem may be. Has anybody seen this error and can help?
Here's my code.
collections.js
PhotosFS = new CollectionFS('photos');
PhotosFS.allow({
insert: function (userId, file) {
return userId && file.owner === userId;
}
});
events.js
Template.createPhotos.events({
"change input[type='file']": function (e, tmpl) {
var file = e.target.files;
Session.set('currentFile', file[0]);
},
"click .save-button": function (e, tmpl) {
var file = Session.get('currentFile');
PhotosFS.storeFile(file, {
name: name,
photographer: photographer,
caption: caption,
});
}
});
I'm guessing it has something to do with storing the file in a session before uploading to the database because if you directly upload the file after a change on the input file it uploads fine. When it is uploaded direct from the input file change event, it uploads as a file. But when it is stored in a session then uploaded, it's uploaded as an object. I guess the CollectionFS chunks don't recognize objects. I don't know. But I do know that for my particular app having the files uploaded directly after the input file change event doesn't make sense.
But I guess I'll have to do this
Template.createPhotos.events({
"change input[type='file']": function (e, template) {
var file = e.target.files;
var fileId = PhotosFS.storeFile(file[0]);
Session.set('currentFile', fileId)
},
"click .save-button": function (e, tmpl) {
var file = Session.get('currentFile');
PhotosFS.storeFile(file, {$set: {
name: name,
photographer: photographer,
caption: caption,
}});
}
});
I won't accept my own answer because I'm still hoping for someone to find a way to work with storing the file in a session before uploading.

We need to scrape VEEC Website for the total number once a week.
As an example, for the week of 17/10/2016 - 23/10/2016 the URL returns the number Total 167,356 when the search button is clicked. We want this number to be stored in our database.
I'm using coldfusion to generate the weekly dates as params and have been passing them like the above URL. But I'm unable to find a query param so that the "Search" button click event is triggered.
I've tried like this & this but nothing seems to be working.
Any pointers?
It seems like for every form submission, a CRSF token is added, which prevents malicious activity. To make matters worse for you, the CRSF token is changed for each form submission, not just for each user, which makes it virtually impossible to circumvent.
When I make a CFHTTP POST request to this form, I get HTML FileContent back, but there is no DB data within the results table cell placeholders. It seems to me that the form owner allows form submission from an HTTP request, but if the CRSF token cannot be validated, no DB data is returned.
It maybe worth asking the website owner, if there is any kind of REST API, that you can hook into...
If you want to use a headless browser PhantomJS (https://en.wikipedia.org/wiki/PhantomJS) for this, here is a script that will save the total to a text file.
At command prompt, after you install PhantomJS, run phantomjs.exe main.js.
main.js
"use strict";
var firstLoad = true;
var url = 'https://www.veet.vic.gov.au/Public/PublicRegister/Search.aspx?CreatedFrom=17%2F10%2F2016&CreatedTo=23%2F10%2F2016';
var page = require("webpage").create();
page.viewportSize = {
width: 1280,
height: 800
};
page.onCallback = function (result) {
var fs = require('fs');
fs.write('veet.txt', result, 'w');
};
page.onLoadStarted = function () {
console.log("page.onLoadStarted, firstLoad", firstLoad);
};
page.onLoadFinished = function () {
console.log("page.onLoadFinished, firstLoad", firstLoad);
if (firstLoad) {
firstLoad = false;
page.evaluate(function () {
var event = document.createEvent("MouseEvents");
event.initEvent("click", true, true);
document.querySelectorAll(".dx-vam")[3].dispatchEvent(event);
});
} else {
page.evaluate(function () {
var element = document.querySelectorAll('.dxgv')[130];
window.callPhantom(element.textContent);
});
setTimeout(function () {
page.render('veet.png');
phantom.exit();
}, 3000);
}
};
page.open(url);
The script is not perfect, you can work on it if you're interested, but as is it will save the total to a file veet.txt and also save a screenshot veet.png.
Pretty new user to Firebase here. I am trying to zip a .wav file from Firebase right now and I am currently stuck on using jszip in order to zip the files from the download URLs I pull from Firebase. The URLs look like this:
https://firebasestorage.googleapis.com/v0/b/instasample-d8eea.appspot.com/o/kick%2F1.wav?alt=media&token=91612541-83e5-4e82-ae1b-b56bc421e36b
Every time I click the download button on my site, this function runs. I successfully get the download URL, and put it into the var urls.
But I get an error that I am not allowed access to this file and an invalid state error. This puzzles me because I am able to manually go to the link and right click -> save target as just fine.
Thank you so much for any suggestions, go easy on me I am new to jszip and Firebase. This is my code:
function download(downloadType) {
//alert(downloadType)
var storageRef = firebase.storage().ref(downloadType + "/" + "1.wav"); //file name
//todo: get 16 random file links, use for loop for thing below
storageRef.getDownloadURL().then(function(url) {
var downloadLink = url; //download link
//////////////////////// do download stuff here ////////////////////////
var zip = new JSZip();
var count = 0;
var zipFilename = "zipFilename.zip";
var urls = [
downloadLink
];
urls.forEach(function(url){
var filename = "filename";
// loading a file and add it in a zip file
JSZipUtils.getBinaryContent(url, function (err, data) {
if(err) {
throw err; // or handle the error
}
zip.file(filename, data, {binary:true});
count++;
if (count == urls.length) {
var zipFile = zip.generate({type: "blob"});
saveAs(zipFile, zipFilename);
}
});
});
thanks to #MikeMcDonald i fixed both of these errors with this post: Firebase Storage and Access-Control-Allow-Origin
I am now getting:
Uncaught Error: This method has been removed in JSZip 3.0, please
check the upgrade guide.
Looks like I can finally move on. Thanks!
I have global array that works just fine and stores the URL's of the chosen images from the user after i click submit in the form.
the problem is when i want to submit another form, the global array will still have the URL's of the previous submission.
what i want to do is to create an array for every user to store his URL's, one he click submit, the array will be dropped or deleted. so if there were multiple users using the same function, every one of them will have his own array to store his URL's
How do i do this?
this is what i have tried but when i click on submit on the form page, nothing happens
first, this is the method that returns the url of the chosen image by the user, the method exists in both folder (both/file.js)
storeUrlInDatabaseSS: function( url ) {
check( url, String );
Modules.both.checkUrlValidity( url );
try {
return url;
} catch( exception ) {
return exception;
}
}
then i created the session variables in the client side (client/file.js)
Session.set("screenshots", []);
Session.set("i", 0);
var screenshots = Session.get("screenshots");
var i = Session.get("i");
and here i store the url in the array
let _addUrlToDatabaseSS = ( url ) => {
screenshots[i++] = url;
Session.set("screenshots", screenshots);
};
and am using Meteor Collection Hook Package
and i added these two lines of code which should be excited after the user press submit, they exist inside "client/files.js" directory
Products.before.insert(function (userId, doc) {
doc.screenShots = Session.get("screenshots");
});
now whenever i click submit nothing happens, i think the problem is because nothing is actually stored inside the screenShots attribute in the collection here
screenShots: {
type: [String]
},
when i set the screenShots attribute to an empty array by default like the code below, the submit button works
screenShots: {
type: [String],
autoValue: function() {
return [];
}
},
I tried to use the other way of using AutoForm.hooks
AutoForm.hooks({
submitPostForm: {
before: {
insert: function(doc) {
doc.$set.screenShots = Session.get("screenshots");
}
}
}
});
the is my form in the .html file
{{> quickForm collection="Products" id="submitPostForm"
type="method" meteormethod="submitPost" omitFields="createdAt, previewImage, screenShots, sourceCode, userID"}}
and this is the method triggered once the user submit the form, it exist in the server side.
submitPost: function (app) {
// Console.log('new App:', app);
check(app, {
title: String,
description: String,
category: String,
price: Number
});
Products.insert(app);
}
for some reason my before hook isn't working and i can't see why!
what am i doing wrong here?
One of the ways to create a global array per user is to use Session. This way it is also possible to persist the data across the app (only client-side).
Simple way to use Session is thus:
Create an array in Session called url_list:
Session.set("url_list", []);
Retrieve the array from Session:
var url_list = Session.get("url_list");
Make changes to url_list:
url_list.push(someData);
Store url_list in the Session again:
Session.set("url_list", url_list);
Note: Session can only be used on client-side and all related code should be on the client-side.
More about Session.
PERSISTING DATA TO SERVER-SIDE:
The best way to persist the url_list to the server, would be to insert a new document into the database collection containing the Session data.
insertToDB = function() {
var url_list = Session.get('url_list');
Products.insert({
'url_list': url_list
});
Session.set('url_list', []); // To empty the client-side list
}
Is there a way to update a part of the URL reactively without using FlowRouter.go() while using React and react-layout?
I want to change the value in the document that is used to get the document from the DB. For example, if I have a route like ~/users/:username and update the username field in the document, I then have to user FlowRouter.go('profile', {data}) to direct the user to that new URL. The "old" route is gone.
Below is the working version I have, but there are two issues:
I have to use FlowRouter.go(), which is actually a full page refresh (and going back would be a 404).
I still get errors in the console because for a brief moment the reactive data for the component is actually wrong.
Relevant parts of the component are like this:
...
mixins: [ReactMeteorData],
getMeteorData() {
let data = {};
let users = Meteor.subscribe('user', {this.props.username});
if (user.ready())
data.user = user;
return data;
}
...
updateName(username) {
Users.update({_id:this.data.user._id}, {$set:{username}}, null, (e,r) => {
if (!e)
FlowRouter.go('profile', {username});
});
},
...
The route is like this:
FlowRouter.route('/users/:username', {
name: 'profile',
action(params) {
ReactLayout.render(Main, {content: <UserProfile {...params} />});
}
});
The errors I get in the console are:
Exception from Tracker recompute function:
and
TypeError: Cannot read property '_id' of undefined
i have been knocking my head for 2 days now in that .
am creating a search engine, am creating queries dynamically using Meteor Framwork, the queries are working fine and when i search i can rebind the UI (Table in My Case) with the dynamic data query output.
however if an insert/update/delete operation occures the data object
and the UI (html Table) is not updating.
which means that the template is not re-rendered when the data object changes.
Template.search.rendered = function () {
Meteor.autorun(function() {
alarmsData = Alarms.find(getSearchSelector($('#searchTxt').val(), $('#startTimeTxt').val(), $('#endTimeTxt').val())).fetch()
console.log("rendered")
//alarmsData = Alarms.find({},{sort: {timestamp: "desc"} }).fetch();
searchControls(alarmsData)
getConsole(alarmsData, ".console")
$('#badge').html(alarmsData.length)
})
}
the get console function is just reading the array from teh search and creating an html table (this is working fine)
as for the begining i am creating a simple query as the default for my search. and then am changing this query whenever user changes the search criteria. i can notice that only the first instance of teh data object is kept and tracked for changes, so if the second search criteria resides within the first one, it's updating the UI, if not nothing happenes
i have used Meteor.autorun(function(){}) function however i traced it's execution with console.log and i can see it's no excuting when i insert data in the database for the same collection.
One, I believe you are trying to use Deps.autorun. Also, there is nothing in your autorun that seems to be dependent on a reactive source. Since alarmsData is taking a snapshot of data it won't care when Alarms has data changing.
Second, I would probably approach this with a redirect. I would compile my data, and redirect to the same page, allowing the server to handle the querying for me. This easily allows you to jump to this page from anywhere else with a prefilled query in the parameters (because the route would then handle it) and also gives a visual change to the navigation bar when a search has happened (just like every other search engine). You would do something like this on a button click:
var query = {},
path;
query.text = encodeURIComponent($('#searchTxt').val()),
query.start = encodeURIComponent($('#startTimeTxt').val()),
query.end = encodeURIComponent($('#endTimeTxt').val()),
// redirect to current path
path = Router.routes[Router.current().route.name].path({}, {
query: query
});
Router.go( path );
In your router you would just pass the query into your server and route as a data object (assuming you are using iron-router):
this.route( "search", {
path: "/search",
waitOn: function() {
return [
Meteor.subscribe( "searchAlarms", _.omit( this.params, "hash" ) ),
]
},
data: function () {
return { "query": _.omit( this.params, "hash" ) };
}
});
This will not only give you the query data that was used for the search (in your template) but the server can now handle the search for you! Your Alarms data now holds all of the documents needed to display to the user and you no longer need to subscribe to all your Alarms. This is also great because it is automatically reactive. So if a new Alarm matches your query filter it will automatically be passed down to the client and displayed to the user without needing to setup any extra dependencies/autoruns.
Note though, that if you are subscribing to Alarms elsewhere you will still need to do filtering client-side.
What a strange meteor code…
The "rendered" code method code is called once you will be rendering the search template
getSearchSelector($('#searchTxt').val() is not reactive, my advise is to use the session variable to put your search criteria inside and use this same session to inject the find parameters inside.
Are you looking for displaying all the alarms Data ?
function getAlarms()
{
var text = Session.get("text");
var from = Session.get("start");
var to = Session.get("end");
var filter = getSearchSelector(text, from, to);
return Alarms.find(filter);
}
Template.search.alarms = function () {
return getAlarms();
}
Template.search.alarmsCount = function () {
return getAlarms().count();
}
Template.search.events({
'keypress input[name=text]' : function(e,o)
{
var val = $("input[name= text]").val()
Session.set("text", val);
},
'keypress input[name=start]' : function(e,o)
{
var val = $("input[name=start]").val()
Session.set("start", val);
},
'keypress input[name=end]' : function(e,o)
{
var val = $("input[name=end]").val()
Session.set("end", val);
}
});
// And your template will look something like:
<template name="search">
Search alarms
<input type="text" name="text" placeholder="Enter your text here…"/>
<input type="text" name="start" placeholder="start time"/>
<input type="text" name="end" placeholder="end time/>
There is {{alarmsCount}} alarms(s);
{{#each alarms}}
Alarm object: {{.}}
{{/each}}
</template>
I Guess its Solved it by using Session.set & get, and automatically subscribing to the Serevr and send the dynamic Query.
Check the below Code
Template.zConsole.rendered = function () {
Session.set("obj", getSearchSelector($('#searchTxt').val(), $('#startTimeTxt').val(), $('#endTimeTxt').val()))
Deps.autorun(function (){
Meteor.subscribe("dynamicAlarms", Session.get("obj"))
console.log("Count from AutoRun ==> " + Alarms.find(Session.get("obj")).count())
})
}
on the server
Meteor.publish('dynamicAlarms',function (searchObj) {
return Alarms.find(searchObj)
})
& it works perfect with less code.
